A cheap and simple solution
Look, if Global Warming is caused by excessive amounts of CO2 in the atmosphere, the solution is simple; PLANT TREES!!! Plants inhale CO2 and exhale oxygen. The bigger the plant, the more CO2 in inhales. Why not revive the old CCC and hire all the unemployed to go out into rural land and plant trees? For that matter, planting fruit and nut trees could combat world hunger. Why not create service organizations that fund the planting of trees in Africa, Asia, and so on? According to the National Academy of Sciences, America is a CO2 sponge -- absorbing 500,000,000,000 tons of CO2 more than it produces, every year -- because of our extensive forests. Why not spread the blessing of forests around? Earth has been badly deforested anyway; if combating Global Warming spurs other countries into planting lots of trees, we could reverse that trend.
